Optical pumping method and apparatus

摘要: In order to avoid problems associated with thermal distortion, loss of energy, and destruction system components, the invention provides a means for producing, first time, high repetition rate, power pulses while avoiding distortion its attendant difficulties. The ability remove heat generated from gain media (lasant material) repeatedly extract energy without accumulation in which causes distortions. avoids distortions by pumping an unheated region every time optical pulse is incident thereon. one aspect, essentially uniformly pumped using instantaneous uniform spatial profile provided multi-mode oscillator. resulting temperature does not create gradients, thus, no occur. invention, total duration lasing or amplification takes place remains beam path. Thus, occur during amplification. Heat preferably extracted at about same rate it lasant material (media).
